how to remove background of image

i have to remove all black colours from it
and make it in white background

reply me how to do
and first test ur self cause when i open it in adobe photoshop,
it shows that this is background image,
not any layers, or foregrounds.
reply me with which software is used and how to remove its black color

in photoshop, duplicate the layer (change to rgb if you have to)
use quickmask and paint the section you want to keep
switch back out of quickmask to have a selection of the image
use layer mask to mask out the background
This will give you an orginal on one layer, and a masked version on the other, turn off the visability of the orginal layer, and create a new layer with the background colour your desire.

Sounds long winded?
The aim is:
1. not to destroy your orginal source material - you may need it again
2. masks are easy to edit if need to add / remove something from the orginal

It's a very time consuming process, but here is the best way to do it, with the best results. This is done using Photoshop CS2, will work in other versions as well.

First: Dupliate the layer, then go over to your history panel and set a history point. This will become very handy here shortly.

Now, on the duplicated layer, goto Filter - Extract. Basically with this tool you are creating a mask of sort around the image. Set the brush size so that is over laps onto the background by about 1/8 inch. I usually work with 20pt brush or so. If you have hair or grass you want to leave in you will need a larger brush to accomodate the wildness of the image. Now draw around your image making sure the brush is almost 1/2 on the image and 1/2 on the background. When your done get the paint bucket and fill the inside of the green line. Hit extract and your done, with this step at least. You will notice that your background is totally gone and some of your image is too, thats ok. We have the nifty history brush. Select your brush size, and choose the history brush. Now carefully use the history brush to redraw the missing parts. Make sure you release the mouse or pen often, as undoing an action may become very frequent here. In the end you will have a perfectly cutout image. This works awesome for things like hair, grass, and anything else that can take eons with the lasso tool and eraser brush.

1. Start by opening an image that you want to remove the background from.
2. Select the Background Eraser tool from the toolbox. It may be hidden beneath the Eraser tool.
3. On the tool options bar at the top of the screen choose a round, hard brush. The size of the brush will vary depending on the image you’re working on. I’m working with quite a large image so I’ve picked a brush size of 100 pixels.

Again, on the tool options bar, set the Sampling to Continuous, the limits to Find Edges and the Tolerance to a low number of about 25 20%. A low tolerance limits erasure to areas that are very similar to the sampled color. A high tolerance erases a broader range of colors
4. Bring the pointer near to the edge of the person or object that you want to remove the background from. You will see a circle with small crosshairs in the center. The crosshairs show the “hotspot” and deletes that color wherever it appears inside the brush. It also performs color extraction at the edges of any foreground objects, so that color halos are not visible if the foreground object is later pasted into another image.
5. Click and drag to start erasing. There is no problem if you bring the circle over the edges between the background and the object (that’s why it’s so cool) but it’s very important that you don’t drag thecross hairs over the edges.

Hi,Background Eraser Tool. If you want to remove a background from an image you're working on, there are many ways to do this using Photoshop. You could select the object you're interested in, copy and paste it to a new layer. Another way to do it is to use the Background Eraser tool.
